The solution to both mechanical and elec-
trical problems
AC motors, “the workhorse of the industry”, that are used to
drive fans, crushers, agitators, pumps, conveyors etc., are
unnecessarily causing unwanted load peaks day in and day
out in production plants all over the world. These violent starts
cause damage in several ways. Among them are:
●
●
●
The financial consequences are considerable: every techni-
cal problem and every breakdown, costs money – in terms of
repairs as well as lost production.
The easy solution to all of these problems is to install an ABB
Softstarter type PSR, PSS or PST. With ABB Softstarters, it is
possible to start and stop smoothly while keeping mechanical
and electrical stresses to a minimum.
Softstarters
From the moment the first electrical motors appeared, en-
gineers have been searching a way to avoid electrical and
mechanical problems that occur using Direct-on-Line and
Star-Delta starters. ABB has been producing softstarters
since the beginning of the 1980’s. The valuable experience
gained since the early 80’s has been incorporated into the
design of today’s product ranges. With the latest series
named PST, ABB has taken a significant step further in soft
starting technology. Matching modern power electronics
with smart circuitry and software, the new PST softstarter
offers superior electronic control of the current and voltage
during motor start-up, in addition to several new design
features.
Electrical problems due to voltage and current transients
arising from Direct-on-Line or Star-Delta starts. Such tran-
sients may overload the local supply network and cause
unacceptable voltage variations that interfere with other
electrical equipment connected to the network.
Mechanical problems that address the entire drive chain,
from motor to driven equipment, to severe stress.
Operational problems, such as pressure surges in pipelines,
damage to products on conveyor belts and uncomfortable
escalator rides.
